Japan Introduces Groundbreaking Fire-Resistant Ventilation Component

In an industry-first milestone, Nihon Jukankyo Corporation, headquartered in Tokyo, has announced the upcoming release of its innovative ep120 Kan Zero component. Scheduled for launch on July 1, 2025, this new product has achieved a 120-minute fire resistance rating—a significant advancement for building materials in Japan. This remarkable enhancement comes at a time when sustainability and carbon neutrality have become pressing societal challenges, compelling the construction industry to shift towards wooden multi-family buildings.

The Need for Advanced Construction Solutions

As urban development progresses, especially in larger cities, the demand for multi-story wooden constructions has surged. In 2019, revisions to the Building Standards Act allowed for wooden structures to be built with fire-resistant designs up to 90 minutes under certain conditions. However, by June 2025, there were no fire-resistant structures available that could achieve timber ceiling ventilation exceeding 90 minutes. This gap in the market highlights the innovative leap made by Nihon Jukankyo with its ep120 Kan Zero product.

Wood, while an increasingly popular choice for construction, faces deterioration issues when exposed to moisture over time. The development of ventilation systems that direct moisture out and prevent water ingress into the structure is vital for the longevity and durability of buildings.

Features of the ep120 Kan Zero

The ep120 Kan Zero not only boasts excellent fire resistance but also incorporates superior water and air permeability features that have been honed through the company’s extensive experience in structural ventilation supplies. With a design price of ¥47,000 (excluding taxes), this innovative component is set to change how builders approach the construction of multi-story wooden buildings.
